===Unopposed Rolls===
;Unopposed Roll:An unopposed roll would be an action where there is a chance of failure, but one is attempting to utilize their skills to overcome this chance, but is not actively contesting another character. Examples include picking a lock, disarming a bomb, or hacking into a computer.
;Determine TN:When declaring an unopposed action, first the player must first determine their  Target Number (TN) for the attempt. This is done by taking the value of an appropriate skill, and multiplying it by the value of the primary attribute attached to that skill. This is the base TN. Next apply any modifiers given by the GM, Gear or by Skill Specialties. This is the final TN use for the roll.
;Roll under Target = Success:Once a target Number is determined, the player makes a Percentile roll, and if the result of that roll is less than or equal to the TN, the attempt succeeds. If the result is higher than the TN, the attempt fails. 
;Degree of Success:If using the optional rules for degrees of success, the closer the result is to the TN without going over, the greater the success. Think of the Showcase game from the gameshow ‘The Price is Right’, in which the object is to guess as close to the actual price of the showcase without going over. This is the objective for rolling for degree of success.
;Desperation:Sometimes situations and modifiers will occur which will reduce the chances of a character succeeding at an attempted action. In such cases, the player may elect to spend Energy points in order to raise the *Target Number* for that roll, thereby increasing the chance that the dice will roll *under* the new Target Number. Any such use of Energy must be declared before the dice are rolled. Note that the player has the right to know what modifiers will be applied to the TN before rolling the dice.
